India is a Monarchy and only one party acts like that internally as well. The Congress is the only party which has one absolute ruler and all others are bootlicking subjects.
In the past people have given power to the BJP (NDA) as well as the third front.
Both those times, as soon as the parties got power the unravelling started as these parties had multiple power centers which dragged them apart and collapsed them.
Modi is nothing on his own unless he has the support of the jackals of the BJP. When the BJP does come to power, the same drama will be enacted. Pretty soon, with the help of Congress from the sidelines and AK to add to the spectacle, the NDA will unravel and we will be back to square one.
I surely have faith in Indians to behave like this and NEVER change! :)
